Just a little clarification... in case anyone wants it.
I dont, and wont say, who makes the guts I carry, unless they are ones I personally make. The reason being... some of my vendors do not want to be known, and that was the only reason they would let me start carrying their guts back years ago. Some dont care, but I just apply the "I dont say" to all the guts I carry, so I dont slip up and say something that might upset a manufacturer sometime.
That being said... the ONLY guts that I make that I sell on my site are the SR101, SR102, and SR103. And the only reeds that are my design are the WCGR1, WCGR2, WCDR1, and WCDR2. I also make the guts for my own calls, but they are not available on the website. Only available with a call.
In addition... so many different places seem to use so many of the same guts, that I really dont even have a clue what all the different names some of these guts might go by. Ive heard rumor this gut or that gut is the same as this or that call makers "such n such" guts... but I cant verify it... since I dont have a set of what ever guts in hand. Im sure someone who knows the various guts, could figure out what is what... and I expect over time, people will. But its just not something I feel is good for me to advertise so I dont slip up and say something I shouldnt.
I guess the biggest thing out of all of this, is I shouldnt be getting credit for guts I didnt design or build... and shy of the SR101, 102, and 103 guts... I didnt design or build em. I know it doesnt clear the water a bunch... but I felt it kind of important people know I am not the manufacturer of most of my guts. I dont do any injection or cast molding here at all at the present time.
 in addition... some of the various guts I carry, I dont get reeds with, and pair the guts with reeds I carry. So Im sure that could confuse things a bit more since a gut might match but a reed might not.
